PipeOps: Why Idempotency Matters
summary
Claims that idempotent pipelines let teams rerun only failed partitions, cut ops time, and eliminate duplicates and data loss by design. Implements: arrival-time partitions written to object storage, transform jobs that detect changes and forbid randomness, and loads that overwrite partitions or use upserts rather than inserts. Validation uses CI end-to-end tests that rerun partitions and assert identical outputs. Platform-level tooling (Kujo AI style stacking of transformers) makes this pattern easy to adopt.
